What to look for in a Full-Stack Developer

Genuine breadth

Confirm they're truly comfortable both ends, not strong one side and weak the other.

Pragmatism

3

Stack fit

Match core technologies, but value adaptability given the breadth of the role.

How to run the hire

1. Define the balance
Be clear whether you need equal front and back, or a lean either way.

2. Review end-to-end work
Look for projects they took from interface to database.

3. Source and approach
Approach passive candidates directly.

4. Test both ends
A practical task that touches front and back reveals the true balance.

5. Reference delivery
Confirm they shipped complete features, not just pieces.
